Specification of Letters Patent.

Patented Mar. 4, 1913.

To all whom it may concern: I

Be it known that I, WALLACE B. WOLFE, United States, residing at of Illinols, have invented a certain new and useful Improvement in slicing-Machinegg of.

which the followin' My invention re atesto improvements,"

drawlngs, wherein a Figure 1 1s a s1 3-3 of Fig. 1.

' Like parts are indicated by like letters in the dr which is mounted the driving s carrying the crank wheel A supports the reciprocating table A on the The vertical housing A, bolts to the frame A, carries at its upper end the sleeve A in which is screw threaded the bearing A". The rotary knife A is mounted on the shaft A in the Ibearing A. .and is driven by a chain riding over the sprocket wheel A" and driven from" the drive shaft by any The bracket B, bolted to the sleeve A, carries thereon the hubB from which projects the o posed flat sides B in opposition to the p unger B. outwardly ressed by the spring B" in the bracket The arm B carries slidably mounted in its outer end the rod C held in position by any suitable means and carrymg the slidable blocks C The flexible curved deflector C is supported at either end on one of the blocks being held thereon by the screw 0 which also engages the rod C and holds. the block'in position. ard C parallel with the edge of the kni e and located just outside ofand a little in front of the cutting edge. This guard is provided at its lower end with the extension G bent outand inwardly toward the'carriage and terminating in a downward extension C which engages the latch C. I

The latch (1 is mounted on a guard D to the frame A and is locatcd immediately in front of the carriage. The meat supportingfoot or guide D is therefron1iand away from slicing machines and; is'illustrated diagrarnff matically in one form in thefacoompanyingi-i de elevation ;of fthe machine; Fig. *2 a sectionalong the lineof Fig. 1; Fig. 3 a section'along .the'li-ne.

ide rail A.

pivotally mountedmounted onthe guard D immediately in front of the cutting edge of the knife and at substantially the same level as the upper, edge of the carriage A This support is provided witha horizontal portion D par: with the topsof the table and with an inclined portionextending downwardly the knife.- .'l. lh-ave j 's'hownladevice as adapted to a -ve ry"i"wellf known type .of slicing machine, :-bl1t "it;;Will be quitejev'ident that it might be adapted to any suitable form of machine, land};wish, therefore, that my drawings be regarded as-in a sense diagrammatic.

, 'The use'and operationof my device are as ing, the knife rotates and the carriage reciprocates backand forth in front of the ife, bringing the meat-in the usual manner-against the rotating cutting edge. The meat slices pass between the cutting edge and the guard, and thus the guard protects meat, but does not interfere with its action upon'the meat, in view of the fact that the guard is placed in front of the cutting edge in such manner that there is space for. the meat to pass between it and the'knife. The

\ flexible curved deflect, r which carried by the guard supp'of ting rod,-contacts-the knife along a'curved line concentric with, but of slightly lesser radius than the cutting edge of the knife and this deflector operates to turn the slice as it is cut away from the ,knife and cause it to fall outwardly and downwardly into any suitable tray or pan, [This deflector thus prevents the passage of meat inwardly toward the axis of the knife, and guards the central portion of the knife of meat therein. The guard and deflector ably mounted vertical shaft, .may conveniently be thrown out of opposition to "the knife by merely rotating them. In order to do this, the downwardly projecting extension on the guard is lifted outwardly out of the latch or hook and the guard is then rotated, carrying with it the deflector. The effective cutting edge of the knife is then sired to use the knifeagainin a slicing operation, the deflector is swung around until the downward extension strikes the inclined portion oithelatch, when follows: When the driving wheel is turn-' and housing and prevents the introduction being both mounted upon a central rota-,4

exposed and may be cleaned. When it is dethe cuttlng edge against anything but the 4 it will, owing to v said only to its elasticity, spring into the latch hook and be held in position, thus compressing the deflector against the back of the knife. These parts are additionally held in position by the pressure of the spring-actuated plunger on the edge of the flat portion of the hub. They are therefore held against the knife by yielding means on either side.

In the preferred form herein shown, the guard is itself made of flexible materialso as to be yielding, but it is also supported at its upper portion by the rod C and the flexible or yielding device connected therewith. Instead of relying upon the flexibility of the lower end of the guard or the projection from the guard, the hook itself might be a yielding structure so as to give a yielding,

support at that end of the guard.- This is illustrate or explain the action of the guard. The deflector is adjustably secured to the vertical rod associated with the guard in such manner that the deflector moves'with the guard andis adjusted so that the two are in proper relation.

While I have illustrated my invention as applied to a slicin machine designed primarily other such objects and materials, still it is quite evident that the same invention might equally well be applied to any device where-- in rotary cutting or grinding wheels are used such as saws, grinders and the like.

I claim:

1. A guard for rotary cutters comprising a rotatably mounted arm, a vertical rod adjustably mounted in said arm, a flexible guard rail integral with said rod and extending outwardly and downwardly and conforming generally in curvature to the cutting edge.

2. A guard for rotary cutters comprising a rotatably mounted arm, a vertical rod adjustably mounted .in said arm, a flexible guard rail integral with said rod and exconforming for the slicing of meat, bread and.

tending outwardly and downwardly and conforming generally in curvature to the cutting edge, and means carried by the machine base for engaging and holding the free end of said guard rail. 7

3. A guard for rotary cutters comprising a rotatably mounted arm, a vertical rod adjustably mounted in said arm, a. flexible guard rail integral with said rod and extending outwardly and downwardlyand conforming generally in curvature to the cutting edge, and yielding means adjacent the pivotal point for holding said guard rail in operative relation to the cutter.

4. Aguard for rotary cutters comprising a rotatably mounted arm, a vertical rod adjustably mounted in said arm, a flexible guard rail integral with said rod and extending outwardly and downwardly and generally in curvature to the cutting edge, and yielding means adjacent the pivotal point for holding said guard rail in operative relation to'the cutter, together with means for holding the free downwardly disposed end of the guard rail.

5. In a cutting machine a rotary cutter in combination with a yielding guard supported at its two ends respectively on opposite sides of the working edge and a deflector mounted so as to be movable with the guard.

6. In a cutting machine a. rotary cutter in combination with a yielding guard and supported at its two ends respectively on opposite sides of the working edge, said guard of yielding material and a yielding support for one end of said guard and a deflector mounted so as to be movable with the guard.

Signed at Chicago, Illinois, this 3rd day of April 1912.
